Abstract

To discover unrecorded diatoms, seawater, sand, and pebbles were collected from the intertidal zone of five tidal flats from 2016 to 2023. Diatoms were isolated from the collected samples, cultured, and the ultrastructure of the cells was observed using a scanning electron microscope. 7 species of unrecorded diatoms, consisting of 3 orders, 5 families, and 7 genera, were discovered: Gomphoseptatum aestuarii, Rhoiconeis pagoensis, Seminavis exigua, Plagiolemma distortum, Staurotropis seychellensis, Biremis sigmoidea, Liriogramma sarcophagus. Among these, four genera, Rhoiconeis, Plagiolemma, Staurotropis, and Liriogramma, are reported for the first time in Korea. L. sarcophagus was separated from the central diatom Asteromphalus and transferred to Liriogramma, but its phylogenetic position has not yet been clearly established.

국내 해역에 출현하는 미기록 규조류를 발견하기 위해 2016년부터 2023년까지 5개 조간대 해역에서 해수, 모래, 자갈을 채집하였다. 채집 시료에서 규조류를 분리 배양하여 전자현미경으로 세포의 미세구조를 확인한 결과, 3목 5과 7속으로 구성된 국내 미기록 규조류 7종을 발견하였다: Gomphoseptatum aestuarii, Rhoiconeis pagoensis, Seminavis exigua, Plagiolemma distortum, Staurotropis seychellensis, Biremis sigmoidea, Liriogramma sarcophagus. 이 중 4개 속, Rhoiconeis, Plagiolemma, Staurotropis, Liriogramma는 국내에서 처음으로 보고하는 속이다. L. sarcophagus는 중심돌말류 Asteromphalus에서 분리되어 Liriogramma으로 이동하였지만 아직 그 계통분류학적 위치는 명확하게 확립되지 않았다.
